Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a viscous material supply device, and more specifically, a tank for accommodating a viscous material required for an adhesive application operation is configured to be swingable. The present invention relates to a viscous material supply device.

(Prior Art) The work of attaching windshields to automobile bodies is
First, wipe off the dirt adhering to the adhesive surface with a cotton cloth soaked with degreasing liquid etc. to clean it, and then apply a primer to the glass side to increase the affinity of the adhesive for the glass surface, and after that , An adhesive is applied to the primer application surface, and the window glass is pressed and adhered to the vehicle body side. For example, in JP-A-61-275071,
There is described an automatic window glass attachment device that automatically performs the series of operations.

By the way, carbon is mixed in the above-mentioned primer in order to improve the adhesive strength and to make it easier to confirm the coating state. Therefore, to prevent the settling of this carbon before applying the primer, and
Sufficient agitation is required to prevent the viscous primer itself from hardening. Conventionally, a stirring blade provided in a tank is externally driven by a drive source, and a primer stirred by the stirring blade is discharged and supplied to a coating device via a pump.

(Problems to be solved by the invention) However, when the stirring blade is provided in the tank, the rotating mechanism such as the drive shaft and bearing is immersed in the highly viscous primer, and therefore the trouble may occur due to adhesion of the primer. Is concerned. Also, especially during stirring, to prevent dissipation of the curing prevention solvent vapor supplied to the primer,
It is necessary to keep the inside of the tank airtight, but as mentioned above,
When the rotation mechanism is provided in the tank, it is not easy to maintain airtightness.

For this reason, it is conceivable that the tank itself is swung to stir the internal primer without providing the above-mentioned stirring blade, but in this case, the discharge of the primer attached to the tank is accompanied by the swing of the tank. There is an inconvenience that the pipe line itself for such things will also swing.

The present invention has been made in view of such circumstances, and prevents the viscous material from adhering to the driving portion and prevents the solvent supplied to the viscous material from being dissipated, thereby improving the efficiency of the viscous material. It is an object of the present invention to provide a viscous material supply device capable of achieving stable agitation and reducing the oscillation of the conduit itself for discharging the viscous material as much as possible.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the adhesive application device of the present invention has a shaft (5) fixed to the upper part of the device, which is swingable about a horizontal axis. Supported viscous material tank (4)
And a viscous material feed pipe (18, 17) connected to the upper portion of the viscous material tank (4) to feed the viscous material from the viscous material tank (4), and a crank mechanism (8) for the support shaft (5). ) And a drive source (7) for swinging the viscous material tank (4) by rotationally driving the crank mechanism (8).

(Operation) In the case of the above configuration, the viscous material tank (4) is swung around the horizontal axis via the crank mechanism (8) which is rotationally driven by the drive source (7). By vibrating the viscous material tank (4) itself, the viscous material inside is agitated. Since the crank mechanism (8) is provided outside the viscous material tank (4) and no rotating mechanism is provided inside the viscous material tank (4), the case where the rotating mechanism is provided inside is provided. There is no trouble due to adhesion, and it becomes easier to maintain the airtightness in the viscous material tank (4), which effectively agitates the viscous material without dissipating the solvent vapor supplied into the viscous material. Will be possible. Moreover, the swing of the viscous material tank (4) is actuated around the support shaft (5) provided on the upper part thereof, and the viscous material pressure feed pipes (18, 17) are connected to the viscous material tank (4). Since it is connected to the upper part, the displacement of the upper part of the viscous material tank (4) due to the rocking of the viscous material tank (4) is different from that in the case where the center of the rocking is set closer to the vertical center of the viscous material tank. As a result, the viscous material pressure pipe (1
The displacement due to the rocking of the viscous material tank (4) of (8, 17) is also reduced as much as possible.

(Effect of the Invention) According to the viscous material supply device of the present invention, there is no trouble due to adhesion, and since the airtightness is easily maintained, the solvent supplied to the viscous material is not scattered,
Effective stirring can be performed. Moreover, the swing of the viscous material feed pipe accompanying the swing of the viscous material tank can be made as small as possible.

(Example) Below, this invention is demonstrated in detail based on the drawing which shows the example.

The viscous material feeder shown in the present embodiment is a viscous material used for adhesion of wind glass and the like, which is capable of effectively stirring and feeding a primer which is a viscous material,
It is configured as follows.

As shown in FIGS. 1 and 2, bearings 3 and 3 are mounted on a pair of support members 2 and 2 which are erected on a base 1, and the upper portions of the viscous material tank 4 are mounted on the bearings 3 and 3. Support shafts 5, 5 projectingly fixed on both sides are pivotally supported, and a viscous material tank 4 is pivotally supported so as to be swingable around a horizontal axis. A flat plate-shaped support member 6 is provided upright on the rear portion of the base 1, and a motor 7 as a drive source and a crank mechanism 8 driven by the motor 7 are attached to the upper portion thereof. The upper end of a rod 10 is pivotally attached to a crank pin 9 (see FIG. 2) that constitutes the crank mechanism 8, and the lower end of the rod 10 has one end fixed to one support shaft 5 of the viscous material tank 4. It is pivotally attached to the other end of the rod 11. A visual sensor 12 (see FIG. 1) for detecting the swing cycle of the viscous material tank 4 is attached to the lower part of the one support member 2. With such a configuration, the viscous material tank 4 can be swung with a predetermined amplitude by adjusting the output of the motor 7 while checking the swing cycle.

The viscous material tank 4 is a bottomed cylindrical body made of tetrafluoroethylene, the upper part of which is covered by a detachable lid 13, and the inside thereof is a cylinder whose upper end is fitted and fixed to the lower portion of the lid 13. An inner cylinder 14 having a circular shape is provided upright. Although not shown, a flexible hose 15 for introducing the primer, to which the solvent vapor for curing prevention is supplied together with the pressurized air, is introduced into the lid 13 from a separately provided primer tank.
And a pipe 18 (only shown in FIG. 1) for connecting a hose 17 for pumping the agitated primer to the applicator are attached, and the discharge port 16a of the pipe 16 is an inner cylinder. The suction ports 18a of the pipes 18 are arranged at the upper part of the pipe 14 so as to face the bottom part of the inner cylinder 14, respectively. The pipe 18 and the hose 17 constitute a viscous material pressure-feeding pipe for pressure-feeding the primer from the viscous material tank 4. In addition,
30 in the figure is a liquid level detection sensor for detecting the amount of primer in the viscous material tank 4.

Like the viscous material tank 4, the inner cylinder 14 is made of ethylene tetrafluoride, and as shown in FIG. 3 and FIG. A hole 19 is formed, and an eaves 20 inclined by about 45 degrees is formed on the hole 19 by bending. This is because when the viscous material tank 4 is swung, the through hole 19 allows the primer to flow in and out of the inner cylinder 14, while the eaves 20 repels or pushes down the surrounding primer. The purpose is to stir the viscous primer evenly and effectively.

According to the viscous material supply device configured as described above,
By the crank mechanism 8 rotated by the motor 7, the viscous material tank 4 is oscillated around the horizontal shaft axis about each support shaft 5 as shown by the alternate long and short dash line in FIG. As described above, the primer inside can be sufficiently stirred. Since the crank mechanism 8 and the rods 10 and 11 for performing this stirring are provided outside the viscous material tank 4, it is easy to make the inside airtight and it is effective that the solvent vapor supplied to the primer is dissipated. In addition, it is possible to prevent troubles such as adhesion of the primer to the rotating mechanism and the like when the stirring blade is provided inside. Furthermore, the viscous material tank 4
The displacement of the upper part of the viscous material tank 4 due to the rocking of the viscous material is significantly smaller than that when the rocking center is set closer to the center of the viscous material tank 4 in the vertical direction. The displacement of the viscous material tank 4 such as the pipe 16 for introduction and the pipe 18 for pumping the primer due to the swing can be minimized as much as possible.
